Question about Sharp Twin Energy EC-12TWT4 Bagged Upright Vacuum

1 Answer

Great hose suction, awful floor performance

Disconnect hose and it sucks wonderfully. Use manual hand attachments and all is well. Horrible performance on the floor. Brush spinning nicely. No Clogs anywhere. I've removed bottom plate to verify suction at end of hard plastic tube. Seal tape looks OK but obviously compressed after years of use. Do I need new seal tape? Where's the suction leaking? Thanks for suggestions!

    This is a tough one because it doesn't fit the standard suspected problems. Plenty of brush torque, even under load, tells me the belt is in good shape. Opened it all up and found no obstructions at all. Dirt inlet is wide open. But still poor performance on floor. I've owned this for several years and it used to do a very good job.

    I have the same problem. I can see no obstruction. Hose tool works fine, brush works, filter is clean. No floor suction. I've taken off the bottom plate and see nothing clogging there. Bag is empty. Where else can I look?

Lose of suction usually means a clog either in the hose, dirt inlet by the brush roll and clogged filters. But a belt that has stretched to where it won't turn the brush roll under load will make it appear as no suction. If you have replaced the belt in a while, I would try that.

Loud rattling noise and no suction


You have something that's been sucked up into the floor cleaning part of the machine... then clogged it off. Be persistent and you should be able to find it and get it out..

My Dyson 41 has just started only sucking through the tube


We've had our DC41 for 4 months now and suddenly noticed no suction at the base as well. Base motor works fine.Thought I'd take one last look before sending in for repair. At the base of the attachment hose near the motor is a small red tab. I depressed it and pulled the entire hose off the motor. Sure enough inside was a eyeliner pencil our daughter had unknowingly vacuumed up. I couldn't see it just peering the length of the hose. Even with a flashlight. You don't see mention of the small red tab but it allows you to see close up rather than peering down the hose if something is lodged near the motor. Apparently this pencil prevented the internal hardware to switch from wand to base suction when the handle is reclined in floor vacuum mode. These vacuums have strong suction and they will pull up the oddest things! Hope this helps!!

Hoover dm6200 blowing air


check your suction hose again, follow it to where it goes into the body of the machine. I assume this will be near where the bagless cannister is. Remove the bagless cannister and look up inside to where the attachment hose should come into the cannister. I believe you are still blocked up there. using a butter knife or something along those lines should free up the blockage.
Also, if that is all clear, try re-adjusting the dirt cannister as it may not be on properly to create your suction flow through the hose.
Good luck and let me know if I can help further.

Floor attachment does not suction, no clog in the hose, hand held works when dettached from floor attachment


Have you checked the floor head? Use a pipe cleaner or twisted metal to carefully and gently see what's in there. It sounds like dirt or something has definately sealed up the main suction channel.

Hoover tc5238 bagless cylinder vacuum cleaner - no suction


You have a clogged hose. Sometimes a Q-tip or something like that gets sucked up and then stuff jams up against it. You can use a long stiff wire with a hook bent in the end to reach the jam and work it loose. Just be very careful not to poke the wire through the hose! Work slowly and get the clog out a bit at a time.

The clogged hose would also account for the red light.

Only suction to attachments


Something is stuck in the throat of the floor head, between the brushes that turn, and where the hose connects at one side (usually right hand side) of the floor head.

Suction


Opening that door and attaching the hose will let the suction go thru that hose. So if when you removed the hose, if that door isn't closed tight will cause you to have a suction problem It has to seal and have no leaks. The other thing when be a problem with the recovery tank not sealing when you put it back on. Other then that, any air leak will cause a suction problem.
